Frozen and thinned bovine pericardium (BP) is a candidate transcatheter aortic valve (TAV) leaflet biomaterial for smaller-profile devices due to their reduced thickness now, however, their mechanical and structural properties still need to be to be fully test. In order to better understand their me...
Unilateral transtibial amputees lose the afferent pathways of the limb when amputation occurs. The addition of vibration has shown to increase sensation on the applied limb. This study looks into how the addition of subthreshold vibration affects amputee gait and posture. Vibration applied to the re...
With the aim to obtain a better understanding of the potential contribution of the plantar-flexor muscle-tendon units to high-jump performance, muscle tendon properties as well as jump kinetics and kinematics in seven elite high jumpers. The results of this study clearly indicate that, different tak...
To quantify balance control during walking, different stability outcome measured based on the (extrapolated) centre of mass ((X)CoM), base of support (BoS) and centre of pressure (CoP) have been proposed. Healthy controls (n=20) and patients with balance and gait problems (n=45) performed two times ...
Basal myosin oscillation is barely dependent on actomyosin cortical tension, indicating that oscillation is mainly from biochemical reaction. During basal myosin oscillation, Rho1 proteins and Rho1 activity are mainly distributed and enriched at and near basal junction and the major control of basal...
Cortical remodeling was shown to be affected by the type and magnitude of physiological stress.¶ This study investigated the effect of compression vs. tension loading on the morphology, mineral¶ content and stiffness of secondary osteonal bone in the proximal humerus of white-tailed deer.¶ Thirty...
The purpose of this study is aimed to compare the facilitate and inhibit effects of Kinesio taping (KT) on muscle hardness and pressure pain of gastrocnemius and tibialis anterior. Forty-five healthy athletes were recruited and allocated randomly to facilitate, inhibit, and placebo taping group. The...
According to the American College of Rheumatology, there are approximately 14 million people suffering from symptomatic knee Osteoarthritis (OA), two million of those being under the age of 45 [1]. Usual treatments for OA consist of total knee replacement, and use of knee orthosis [2]. However, the ...
The effect of cerebellar transcranial direct current stimulation (c-tDCS) on online and offline learning of complex multi-joint movements is relatively unexplored. This study employed a two-session double-blind SHAM-controlled design to examine total, online, and offline learning effects of c-tDCS o...
PURPOSE: To determine whether compression garments are more effective in facilitating recovery. METHODS: 15 male college student participated in this study. The subjects performed experimental trials with a compression garment (CG) or without a CG (CON) during the recovery period after the deep squa...
This study investigated the type and number of haptic feedbacks that would yield better subject perceived accuracy during walking and running. Findings suggested staggered haptic feedback would lead to higher accuracy than continuous feedback especially when more than two motors were used.
External cueing without variability fails to address the variable patterns typically observed in healthy gait, and rehabilitation goals are depending on the degree of synchronization. The ability to synchronize could be improved when coupling systems match in their time-based statistical properties....
The present study investigated the lower limb joint angle dynamics during walking and running at a range of speeds. The joint angle dynamics was assessed by the largest Lyapunov and correlation dimension. It was observed that while altered speed affected the attractor dynamics, changes in gait mode ...
This investigation explored the geometrical customisation of the established BOX total ankle replacement (TAR), to minimise the critical issue of prosthesis-bone size mismatch. A customisation procedure was developed and applied in eight patient-specific bone models through in silico implantation. T...
A delivery van ingress strategy using the A-pillar handhold instead of the steering wheel as hand support reduces reaction forces at the intermediate entrance step by approx. 17 %. The applied force at handhold or steering wheel remained comparable for both movement patterns. Therefore, a strategy u...
The purpose of this study is to investigate for the effect of functional compression tights (FCT) using a biomechanical method. Eighteen limbs of 10 healthy male participants were included. Participants were required to perform straight-line walking trials at usual walking speed. A three-dimensional...
A systematic review of the murine tibia axial compression model was carried out in order to explore the effect of static preload (SPL) on bone adaptation. SPL is a recently identified potential inhibitor of loading-induced bone adaptation [1]. Of 1766 initially identified references, 15 articles met...
Inertial measurement units (IMUs) were used to quantify the effects of military clothing and individual equipment (CIE) on both expert and novice marksmen. The focus was to capture the differing movement strategies used to mitigate the effects of CIE on marksmanship performance. A primary hypothesis...
The human foot arch has been suggested to store and release elastic energy during locomotion. However, experimental evidence for this assumption during jumping is missing. Thus, the relationship between the maximum deformation of the arch and jump height during countermovement jumps was investigated...
Inertial measurement units (IMU) are used to calculate joint kinematics. This study demonstrates that subject-specific calibration movements based on a patient’s function and ability including limited range of motion and speed are sufficient for defining body segment coordinate systems at the pelv...
Ligament rupture is among the most common musculoskeletal problems. Nevertheless, an ideal graft transplant helps to bring the patient back to normality. Nowadays, two types of graph transplants are used, however, they both present disadvantages: autograft, tends to lose their mechanical resistance ...
This study dealt with temperature investigation during drilling into the artificial bone. The main aim was to develop suitable method for experimental temperature measurement. The experiments were realized with several different dental drills, and different drilling conditions (speed, cooling etc.).
Sensitivity of the force in the anterior cruciate ligament (ACL) to quadriceps (Q), lateral and medial hamstrings (LH and MH) forces during drop landing was evaluated using a finite element (FE) model of the knee.
The study used the quantified assessment, feasible flexible region (Figure 1), to establish the relationship between the center of mass (COM) and base of support BOS). Eight subjects with MS were recruited. An 8-camera motion capture system (Vicon, UK) was used to collect their full-body kinematics ...
The effect of diabetes on the ability of older adults to respond to external perturbations is not well documented. The purpose of this study was to determine if stepping threshold (ST) could be quantified in a clinical setting in older adults with diabetes and if it provided unique information regar...
The purpose of this study was to investigate the effect of Kinesio taping on the functional movement for healthy athletes. 29 athletes were recruited and randomly distributed to the Kinesio group and the placebo group. The Deep Squat test and Inline Lunge test of Functional Movement Screen (FMS) wer...
The material properties of the intact human liver using unconfined compression with varying strain rates were measured in this study. The liver modulus was not strain rate dependent between 1%/s and 25%/s. Failure stress increased by 20% and failure strain increased by 46% when the strain rate was i...
Clinical and experimental locomotor learning is often done on treadmills, which are commonly equipped with handrails. However, the effects of holding handrails on locomotor learning are unknown. Here we study the effects of handrail holding on split-belt adaptation in four groups: 1) Holding side-mo...
The purpose of this study was to examine the effectiveness of different aquatic activity instructional methods for autistic children for motor skills development. Autistic children were evaluated over a three-week period of swim lessons between an upper extremity instructional method vs a lower extr...
